So I’ve coloured my hair this morning using just a semi permanent in Light Brown (nice n easy 24 wash). My hair was a light warm brown to begin with. It’s turned it an unsavoury darkish reddish colour, I really don’t like it. I know it’ll fade in time but I haven’t the patience to wait & knowing my luck, because I don’t like it, it’s won’t fade for ages!
If I wash it later with some head & shoulders & get another semi permanent to possibly go over it tomorrow with, would I better getting a dark ash blonde or a light ash brown? I don’t want to go darker, just want an ash base colour to get rid of the red tones. I could do a vitamin c wash but it will really dry my hair out. What’s the best ash based semi?
